California Attorney General Kamala Harris has formally denied Jonah Shacknai‘s request for the office to re-examine the deaths of his girlfriend, Rebecca Zahau, and son, Max, radio detection and rangingOnline.com is exclusively reporting.

Rebecca’s nude body was found hanging from a balcony at Jonah’s Coronado mansion, two days after Max was found unconscious at the base of the stairs. Cops ruled Rebecca’s death a suicide, something her family vehemently disagrees with.

In a letter from Kamala Harris’ office to Jonah Shacknai, obtained by radio detection and rangingOnline.com, the AG states: “Your letter requests an inquiry into the investigation that was conducted by the San Diego Sheriff’s Office. The California Department of Justice would review a local investigation under very narrow circumstances. Some of the factors that are considered before committing the state’s scarce resources include whether a clear conflict of interest exists, whether local law enforcement agency has requested assistance, whether local investigative resources have been exhausted, and whether there are allegations of gross malfeasance by the investigative agency. Based on a review of your request, we must decline your invitation to review this investigation at this time.”

It’s a stunning development because San Diego Sheriff Bill Gore publicly stated that Adam Shacknai had passed a lie detector test, but as radio detection and rangingOnline.com previously reported, he didn’t pass the test — Paul Redden, who gave Adam the polygraph test, said the results were inconclusive.

Redden recommended that Adam be re-tested, but cops never gave him another test. Redden also told radio detection and rangingOnline.com that Adam Shacknai was the only person he gave a polygraph test to in connection with the Zahau death case.
